Subject: Oyster Creek Generating StationIndependent SpentFuel Storage Installation Annual Report

Reference: Building Permit; Appeal 93-40 (after remand)

The above referenced Building Permit requires the Oyster Creek Generating Station to submitroutine monitoring reports to Lacey Township on an annual basis. Enclosed is the TemperatureMonitoring and Radiation Survey data as required by Condition 10 of the Building Permit, and thenumber of spent fuel assemblies in dry storage as required by Condition 11 of the-Building Permit.The status of Federal Govemmentrs plans to site a permanent spent fuel repository is alsoprovided, as required by Condition 17 of the Building-Permit. This fulfills the reportingrequirements for the year 2008.

If any further information or assistance is needed, please contact Richard Milos at 609-971-4973.

Independent Spent Fuel Storage Installation (ISFSI) Buildina Permit Condition Ten:

"The applicant shall provide to the township on a yearly basis, written records revealing alltemperature and radiation measurements. The applicant shall further advise of any and all repairsmade to the concrete modules."

Oyster Creek Generating Station Reply to Condition Ten:

The temperatures of the loaded, concrete, Horizontal Storage Modules (HSMs) are monitored dailyand are part of the station's surveillance records. The temperatures of the loaded HSMs can be upto 30 degrees higher than the unloaded HSMs depending on the heat load of the spent fuel loaded.During the summer months, the highest concrete HSM temperatures were less than 120 degrees.This is well within the design limits of the HSMs and represents an actual heat loading of about 7.5KW.

The following graphs represent average monthly temperature data for the period from October2007 to September 2008, for the HSMs we loaded in 2002 (# 1-4), the HSMs we loaded in 2003(# 5-8), the HSMs we loaded in 2004 (# 9-11), and the HSMs we loaded in 2005 (# 12-16). HSMs#17-18 remain empty and are at ambient temperatures.

The highest radiation measurements on the vertical face of the HSMs were 2 mr/hr gamma and<0.1 mr/hr neutron. The highest gamma dose rate at the opening between the HSMs (birdscreens) was 6.1 mrem/hr. These readings are well within the design limits of the HSMs. The roofof the HSMs is a posted radiation area and is not readily accessible. The highest radiation levelsat the ISFSI security fence facing Route 9 was <0.2 mr/hr gamma and <0.1 mr/hr neutron.Radiation survey data sheets are included following the temperature graphs.

We are currently installing the remaining two HSMs (#19-20), with a planned loading of four spentfuel canisters into HSMs #17-20 during 2010. This will complete the existing Independent SpentFuel Storage Installation reviewed under the Building Permit, Appeal 93-40 (after remand).

There were no repairs to the concrete modules since the last report.

Independent SDent Fuel Storaae Installation Buildina Permit Condition Eleven:

"The applicant shall provide to the township on a yearly basis, the specific number of spent fuel rod

assemblies which have been moved into the dry storage facility."

Oyster Creek Generatina Station Reply to Condition Eleven:

There were no fuel assemblies loaded into the ISFSI prior to 2002. During 2002, 244 fuelassemblies were transferred to the ISFSI. During 2003, 244 additional fuel assemblies weretransferred to the ISFSI. During 2004, 183 additional fuel assemblies were transferred to theISFSI. During 2005, 305 additional assemblies were transferred to the ISFSI. No fuel assemblieshave been loaded into the ISFSI since 2005. The Oyster Creek ISFSI currently contains 976 fuelassemblies.

Independent Spent Fuel Storage Installation Buildina Permit Condition Seventeen:

"The applicant shall submit a report to the Township of Lacey no less than annually as to the statusof the efforts of the Federal Government to site a permanent spent fuel repository."

Oyster Creek Generating Station Reply to Condition Seventeen:

The Department of Energy has submitted a license application for the Yucca Mountain Repositoryto the Nuclear Regulatory Commission on June 3, 2008. The best achievable schedule foroperation is 2017.
